SOLUTION: The fixing device has a fixing member, a pressure member, a first heating member which primarily heats the fixing member, a second heating member which auxiliarily heats the fixing member, and a third heating member which heats the pressure member. Then rated outputs P1 to P3 are so related that P1>P2≥P3, where P1 is the rated output of the first heating member, P2 is the rated output of the second heating member, and P3 is the rated output of the third heating members. Further, the second and third heating members are connected in series to a voltage application device. In this case, the first heating member is arranged at the fixing member, so the temperature of the fixing member is prevented from suddenly becoming high to prevent a defect in fixation from being caused.
